Answer:
Step-by-step explanation:
<u>Probability of 1 is 1 out of 6:</u>
<u>Probability of less than 3 is: </u>
- 1 or 2 out of 6 = 2/6 = 1/3
<u>P(1, less than 3) is</u>
First, take half of the coefficient of 18x then square it.
18 / 2 = 9
9^2 = 81
So, D. 81 is the answer.
1,680 divided by 400 = 4.2
So we know that Xian has done 4.2 laps.
4.2 divided by 14 = 0.3
0.3 x 100 = 30%
Therefore, Xian has finished 30% of the run
